It's Manic Monday time at Wimbledon as Roger Federer sets the ball rolling at Centre Court with a fourth round match against America's Steve Johnson. With all 16 of the fourth round matches in the men's and women's singles taking place on Monday, Federer will not want to be one of the headline makers for the wrong reasons.

The Swiss maestro has looked good with every passing match, growing from strength to strength with every ball hit on his favourite grass courts, and with Novak Djokovic now out of the Wimbledon picture, the seven-time champion will be extra motivated to perform on Monday, while also being aware of the pitfalls of complacency.

"The goal was to get to the second week somehow," Federer, who missed the French Open with injury, and came into Wimbledon with a fitness cloud hanging over him, told reporters. "Now I won nine straight sets, which is great.

"Plus with the wet weather that we've seen, the opponents that I had, never quite sure. But I was favored if I would be feeling 100%, great, yes, you would maybe expect that. But I didn't know for myself where I was, so I am happy where I am now."

Where he is now is in a strong position after swatting aside Dan Evans in round three. If the No.3 seed continues that form into this match on Monday, there will be only one winner.

Johnson, though, will not be an easy opponent. The world number 29, but unseeded at SW19, has beaten some pretty accomplished players en route to the fourth round. Having seen off the challenge of Malek Jaziri in the first round in straight sets, Johnson breezed past the experienced Jeremy Chardy in round number two, winning the match 6-1, 7-6 (8-6), 6-3.

However, his biggest and most impressive win came in the third round, when he got the better of the man known as the "Baby Federer" – Grigor Dimitrov. Having lost the first set in the tiebreak, Johnson came back to level the match, also on a tiebreak, before taking the final two sets 6-4, 6-2 to top the Bulgarian.

So, Johnson will be in confident mood when he runs into Federer, but then when you play one of the greatest of all-time, confidence alone will not do, a little rub of the green is also necessary, and the American will certainly hope luck is on his side come Monday.
